<p><a href="http://programmers.stackexchange.com/questions/89839/how-do-i-determine-the-runtime-of-a-double-recursive-function">This question</a> is considered on-topic on Programmers.SE, and I don't understand why.</p>

<p>It is a question about computer science, not a question about programming or programmers. It's something a good programmer should know, but it's not programming (in the same way, using a computer is definitely required of a programmer, yet computer usage isn't programming). It's a subject where an expert would be a computer scientist, not a programmer.</p>

<p>Furthermore, it's an objective question. The run time of a function is a perfectly well-defined notion (at least in a given context, and the choice of context isn't relevant here). There may be more than one way to compute it, it would still be the same thing being computed — this isn't about making a design choice.</p>

<p>So, going by the <a href="http://programmers.stackexchange.com/faq">site FAQ</a> as well as the overall tone and audience of the site, this question doesn't belong here. I <a href="http://meta.stackexchange.com/questions/80023/where-on-se-to-discuss-computer-science">don't think there's currently a site in the Stack Exchange network that's really appropriate for it</a>¹, but the closest, and <a href="http://meta.stackexchange.com/questions/80023/where-on-se-to-discuss-computer-science/80058#80058">officially-sanctioned</a>, is <a href="http://stackoverflow.com/">Stack Overflow</a>.</p>

<p>Why, then, is this question not migrated to Stack Overflow?</p>
